Hello Gilbert,
I enjoy having a reader in France – how did you discover my blog?
You didn’t ask for this advice, but I’d like to give it anyway: you say you’re ” very bad at rhythm”…. how about if you changed that slightly to say, “I’m getting better at rhythm”, or even “I am working on my rhythm”.
It’s a very subtle change, but I believe it “opens the door” to learning – it’s better than repeating something you don’t really want to be true.

That being said – “America” is a rather hard song. I am teaching it in my class, and it moves along quickly, and there are some tricky areas. I hadn’t planned on doing a tutorial on the whole song until I thought that everyone got the hang of the rhythm…

That being said – perhaps at some time I can delve into it a bit more for those like you who wish to challenge themselves.

Have a great day over there in France.
By the way, I was over there in 1981 – I went to Paris and the Eiffel Tower, of course, and rode the subway around. It was my first time away from home.
